# Variance Components Save to New File

You can save some results of this procedure to a new IBM® SPSS® Statistics data file.

**Variance component estimates.** Saves estimates of the variance
components and estimate labels to a data file or dataset. These can
be used in calculating more statistics or in further analysis in the
GLM procedures. For example, you can use them to calculate confidence
intervals or test hypotheses.

**Component covariation.** Saves a variance-covariance matrix
or a correlation matrix to a data file or dataset. Available only
if Maximum likelihood or Restricted
maximum likelihood has been specified.

**Destination for created values.** Allows you to specify a
dataset name or external filename for the file containing the variance
component estimates and/or the matrix. Datasets are available for
subsequent use in the same session but are not saved as files unless
explicitly saved prior to the end of the session. Dataset names must
conform to variable naming rules. See the topic Variable names for more information.

You can use the `MATRIX`

command to extract the
data you need from the data file and then compute confidence intervals
or perform tests.
